Abstract Education and training interventions can be evaluated through the success of learning outcomes. Kirkpatrick's four-level model is a widely accepted and highly popular evaluation tool. However, some criticise the model's shortcomings. This article will examine the extent to which the four-level model can evaluate design and technology students' learning about aesthetics after an intervention by reporting our use of an augmented version of the four-level model. We examine the results in terms of students' reaction to the intervention, their long-term learning and their behaviour changes by studying their visual analyses and drawings through segment codes. We found that, in order to uncover the obscurities imbedded in aesthetics and to explicate the complexities, we could not use the four-level-model on its own, but had to revert to a more augmented version.

As Athapaskan-speaking people with a lifestyle distinct from other Southwestern groups, Navajos, upon entering the Southwest in the sixteenth century, are thought to have begun a process of culture change that persists to this day. The anthropological view of Navajo culture is that it is a synthesis of Athapaskan and Puebloan culture traits, and early archaeological studies of Navajo culture reinforced this view. Navajo archaeology continues to suffer from a general lack of Navajo perspectives on their own history andarchaeological record. I examine Navajo identity expressed in the built environment and the negotiation of intrusive federal Indian policies in the late nineteenth and early twentieth centuries using narratives from a ceremony called the Blessingway and theories of agency, practice, history, and structuration. Environmental, architectural, dendrochronological, artifactual, and historical data collected from 393 hogan sites recorded in the Four Corners area during the Navajo Land Claim Project in the 1950s comprise the basis for my study. Data analyses indicate that in spite of the imposition of policies designed to alter Navajo lifeways and relationships with the landscape, American colonial interactions did not dramatically alter the core of nineteenth and twentieth century Navajo culture. The dialectic between colonial policy and traditional Dine culture resulted in persistent architecture, settlement patterning, and decision making about movement over landscapes in spite of conflicts over land and water. Historically, theories and methods arising from the Western tradition have been the main avenues through which archaeologists interpret and make sense of the Indigenous past in North America. The growing body of modern literature in Indigenous archaeology now consciously includes, and often takes as its starting point, Indigenous perspectives on the past, and the practice of archaeology in America. Practitioners of Indigenous archaeology seek to strike a balance between Western perspectives and Indigenous worldviews and to increase the participation of Indigenous people in the discipline. My study is an attempt to weave together Indigenous and Western philosophies in a mutually beneficial manner.

The purpose of this thesis was to develop the first examples of multifunctional triarylboron-functionalized 8-hydroxyquinoline, their respective aluminum (III) complexes, Al(1)3 and Al(2)3, and diboron analogues, B1 and B2. There was particular focus in investigating the electron accepting characteristics of these systems for potential use as electron transport materials (ETMs) in organic light emitting diodes (OLEDs). The first part of the thesis will discuss the aluminum complexes. Through the introduction of the triarylboron moiety these derivatives of the well-known ETM tris(8-hydroxyquinoline)aluminum (Alq3) exhibited better electron accepting properties than the parent compound. Furthermore, the complexes were able to act as sensors and indicators towards soft Lewis acids such as CN- and hard Lewis acids such as F-, respectively. First the structures of the compounds were investigated using COSY NMR, leading to the discovery that similar to Alq3 the new aluminum complexes possessed the commonly observed mer-isomeric form. Furthermore, their photophysical characteristics were investigated using UV-Vis and fluorescence spectroscopic measurements. The solid state fluorescence quantum yield of Al(1)3 (Φ=0.06) and Al(2)3 (Φ=0.02) were measured and compared to Alq3 (Φ=0.14). In order to better understand these results and gain insight into the electronic transitions of the aluminum complexes, DFT calculations were employed using the B3LYP/6-31G* level of theory. The second part of the thesis will discuss the only examples of diboron-functionalized 8-hydroxyquinoline complexes to date, with one three-coordinate and one four-coordinate boron moiety. Based on CV measurements and DFT calculations, it was discovered that the LUMO of the diboron compounds were lowered substantially compared to their aluminum analogues discussed earlier. More interestingly, it was found that only B1 has any contributions to its LUMO from the triarylboron moiety, leading to the slightly stronger electron accepting ability of B1 compared to B2. Furthermore, these compounds were both able to act as sensors towards small anions such as F-. / Thesis (Master, Chemistry) -- Queen's University, 2011-09-21 08:43:10.543

Nicolas Poussin's landscapes, The Four Seasons, 1660-1664, have been the subject of extensive analysis because of their enigmatic character and the modulation in Poussin's style in his last years. The meaning of these representations has, however, remained cryptic and, to some extent, neglected. / This thesis attempts to make a contribution toward unravelling the mystery of The Four Seasons. These profound works reflect Poussin's religious persuasion, knowledge of which is essential to an understanding of them. Poussin's religious convictions, however, are difficult to discern with any precision; for, although he died a Catholic, he was closely associated with the progressive thinking that influenced religious belief in the Baroque age, much of which was rejected by the Church of Rome. / Nevertheless, Poussin was undoubtedly a devout Christian, inspired particularly by the early Christian Fathers and Stoics. It is in nature, above all, though, that he perceived God's presence and message which he strove to capture in his "altarpiece" to the seasons.

Two special classes of solutions to the Yang-Mills equations are studied in this thesis; Hermitian-Einstein connections on holomorphic bundles over Kahler manifolds, and self-dual connections on bundles over Riemannian 4-manifolds. We give a new proof of a theorem of Narasimhan and Seshadri, which characterizes those holomorphic bundles over an algebraic curve admitting projectively flat connections, and describe a conjecture of Hitchin and Kobayashi that would extend this to Hermitian-Einstein connections over any smooth projective variety. This conjecture is proved to be true for the simplest interesting case: bundles of rank 2 over ℙ². Moduli spaces of self-dual connections are studied from the point of view of differential topology, For bundles of Chern class -1 over a simply connected 4-manifold this moduli space can be compactified in a straightforward way and is, in a generic sense, an orientable manifold with quotient singularities. Applying the theory of cobordism to this moduli space we deduce that there are severe constraints on the matrices which can be realised by the intersection pairing on the second homology group of a smooth 4-manifold.

In 2006, an amphoteric molecule containing both an aldehyde and an unprotected amine was reported in the Yudin group by Dr. Ryan Hili. The unprotected aziridine aldehyde exists as homochiral dimers. Furthermore, due to the reversibility of the hemiacetal formation, the free aldehyde is available to undergo a wide array of reactions including an Ugi multicomponent reaction to give the final peptide macrocycle. Thus far, the mechanistic pathway involved in the Ugi reaction between S-trans aziridine aldehyde dimer and L-amino acids in the presence of tert-butyl isocyanide has given high diastereoselectivity whereas low diastereoselectivity is observed if the aziridine dimer is of the opposite stereochemistry. Herein, preliminary results show that a S-cis aziridine aldehyde with either a D or L-secondary amino acid gives high diastereoselectivity showing that the reaction is under Felkin-Ahn control.
